if you're going to own a gun, you must learn to use it properly. >> i want you to lean into it. >> reporter: i'm not sure about my own comfort level, not yet, anyway. but as i look at statistics, i see crime did not go down under the u.s. assault weapons ban. i don't have an answer to the gun debate. but with some 300 plus million firearms in the u.s., it would seem those fighting for all or nothing may not hold the answer either. you know, kate, this issue is so complex. there are so many things to consider. even something as basic as the number of gun owners, i tried to find that answer, well, no one knows. states, counties, cities, they all have their own gun laws. in some places, you have to register, in other places, you don't. so really the people who are going to be looking at legislation and what to do and what to ban and how to go about it, they have a very, very difficult, very complicated job ahead of them, kate. >> it's very complicated, but i will say, deb, i love that you set out to do this piece.
